How to clear the entire model

[Andrew Symington]

Hi There

I'm using LocalStorage to temporarily store my model data. I would like my app's constructor to clear all records (on storage and in the model). Is there a quick way to achieve this? I see that the clear() method in Batman.Model just clears the identity map, but the data remains in local storage. Is there any way to clear the local storage as well?

Cheers

Andrew

Andrew,

You can clear all local storage using localStorage.clear(). http://stackoverflow.com/questions/7667958/clear-localstorage

If you need to clear all for a particular model then I believe you will need to iterate over each object and destroy it.

Hi Jeff

This is what I've been doing so far, and it seems to work, even though its a bit clunky.

records = MyApp.MyModel.get('all')

records.forEach (record) ->

  MyApp.MyModel.find(record.get('_id'), (err) ->

    if (err)

      console.log "Cannot find record " + record.get('_id')

    ).destroy()

MyApp.MyModel.clear()

So, from what I can tell, this is probably a simpler solution.

MyApp.MyModel.clear()

window.localStorage.clear()

Thanks for the help!

Cheers

Andrew
